A '''nut''' in [[botany]] is a ''simple dry [[fruit]]'' with one [[seed]] (rarely two) in which the [[ovary (plants)|ovary]] wall becomes very hard (stony or woody) at maturity, and where the seed remains unattached or unfused with the ovary wall.  Most nuts come from [[carpel|pistils]] with ''inferior'' ovaries (see [[flower]]) and all are ''indehiscent'' (not opening at maturity).  True nuts are produced, for example, by some plants — families of the [[order (biology)|order]] [[Fagales]].
